D3DWDDM2_0DDI_VIDEO_CAPABILITY_RECOMMEND_DECODER_DOWNSAMPLING structure (d3d10umddi.h)
D3DWDDM2_0DDI_VIDEO_CAPABILITY_RECOMMEND_DECODER_DOWNSAMPLING is used by the user-mode driver to recommend downsampling parameters that can be used to decode the stream in real-time. The driver provides these capabilities when its PFND3DWDDM2_0DDI_QUERYVIDEOCAPABILITIES function is called.

Members
pInputDesc
[in] Pointer to a D3D11_1DDI_VIDEO_DECODER_DESC structure containing the decode profile used and the resolution and format of the reference frames. This is the resolution/format to be downsampled (e.g. 4K, DXGI_FORMAT_P010).
InputColorSpace
[in] A D3DDDI_COLOR_SPACE_TYPE value that specifies the color space information of the reference frame data.
pInputConfig
[in] Pointer to a D3D11_1DDI_VIDEO_DECODER_CONFIG structure containing the configuration data associated with the decode profile.
pFrameRate
[in] Pointer to a DXGI_RATIONAL structure containing the frame rate of the video content.
pOutputDesc
[out] Pointer to a D3D11_1DDI_VIDEO_DECODER_DESC structure in which the driver returns the recommended resolution and the format of the output/display frames.
The decode profile (Guid) member of pOutputDesc can be ignored.
OutputColorSpace
[out] Location in which the driver returns the recommended D3DDDI_COLOR_SPACE_TYPE color space information of the display frame data.
Remarks
The driver recommends the down sample parameters such that the video stream can be decoded in real-time. If no down sample solution exists that can result in real-time decode, the driver should recommend the configuration that is closest to the real-time solution.
